Conclusions
During the heating of rotary kilns it is desirable to use self carburation of natural gas. In this case there is an increase in the temperature in the sinter zone, and an improvement in heat exchange, a reduction in the preparatory zone for the fired material, and an increase in the length of the sinter zone; there is also an increase in the dwell time of the material in the high-temperature zone. It is necessary to carry out wider investigations on the rational combustion of natural gas in rotary kilns for burning various types of refractory materials. Attention should be drawn to the development of economic methods of carburation or self carburation of the natural-gas flame in rotary kilns, and compact, satisfactorily operating burner devices giving luminous flames.
